HORATIO KEYES, OF TERRE HAUTE, INDIANA. Letters Patent No. 59,843, dated .November 20, 1866.

sPECIFIcATion-. T0 .ALL WHOM IT MAY CONCERN:

Beit known that I, HoRArIo KEYES, of Terre Haute, in the county of Vigo, and State of Indiana, have invented anew and improved Apple-Paring Machine, and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enablev others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this speciiication, in which- Figure 1 is a side view of the machine attached to a table for operating.

Figure 2 is a front view of the same.

Figure 3 is a plan.

Figures 4 and 5 are inverted plans in different positions of the mechanism.

Similar letters of reference indicate like parts.

This invention relates 'to-improvements in the lmechanism -of apple-paring machines,whereby they are made double-acting and capable of paring apples much faster than ordinary 'single-acting machines. The operation is such that the paring knife having passed from the back to the front of the apple'holder, and thus pared one apple, vis thrown down out of .the way so that the pared apple can be removed and another put on the fork in its place, to he pared on' the return,d movement of the knife t`o its first position. In this manner the machine pares continuously and no time is lost in the reverse movement of the paring knife, as in ordinary machines. A is the supporting frame ofthe machine fastened in the usual way to a table by the thumb-screw a B is the driving wheel turned by the crank b C is the holding fork rotated by the pinion D, which gears into the driving wheel B. On the inner end of the short shaft of the driving wheel B, is placed a small bevel wheel c which engages in a larger horizontal bevelwheel c', upon the upper side of which is affixed concentrically 2 segmental spur Wheel d, which engages in another segmental wheel d', supported by the axis e, on a projectiox A shown infigs. 2 and 4i On the segmental Wheel d is mounted the paring knife f, aiiixed to the arm f which works at the lower end on the axis g, around which is Wound a spiral spring, g1. On the bottom of thf knife arm f are several cogs which engage in corresponding cogs on the segmental edge of a small lever brak h, which lies under the axis g, and is pivoted by the axis e. On the end of theax/is e, opposite the segmenta wheel d, is affixed another segmental spur wheel z',-iigs. 4 and 5, which gears into a curved rack j, cn tin inner side of the rim of an eccentric rack frame c, which centres and moves on a pivot l, set in the frame A near the bevel wheel c, as shown in f1g.'3. On the under side of the bevel wheel c', a pin, m, projects oppo site the last cog on one side of the segmental set of cogs upon it, which pin m catches against the projectin,` arm n, on the inner side-of the rack frame c, for moving it forward as the bevel wheel c rotates, giving aA retur movement of half a revolution to the paring knife e, which is the peculiar and essential' feature of this invention It will beobserved when the machine is operated that thebevel Wheel c' is moved forward as indicated by th arrows in gs. and 5, that the last cogs in the segment d, are engaged in the last cogs in segment d, afte having made half` a revolution of the bevel wheel c', which half revolution has carried the paring knife e, fro! the bottom to the top of the holding fork C, and thus pared one apple. At this point of the operation of th machine the lever brake z, comes into play by bearing its extremity against the periphery of the bevel whe: c', the effect of which is to turn the lever, brake a little on its pivot e, and by means of the cogs in its segment: edge Working inthe cogs on the bottom of the knife arm f', throw the arm and paring knife down dat out of th way the moment the' apple has been pared by the rst-half revolution of the bevel wheel c. Just as the cog on the segments d d', have passed each other so that the segment d', is released from th'e segment d, the pin n on the lower side of the bevel wheel opposite thc last cog on the segmental wheel d, takes up the movement b catching into the crotch of the projection n, on the inner side of the eccentric rack frame k, and while the bev wheel c' continues to revolve in the same direction as before, the pin m bears against the projection n, al: thus pushes the rack frame c forward, when the cogs'inthe rack j engage in the cogs in the segmenti, iig 4 and 5, and give it half a revolution, thus reversing the movement of the wheel z' in the rack j, and also of tl paring knife, Which then resumes its upright position and is carried back :to its starting point by the remainir half revolution of the bevel wheel c. It will be observed that as the bevel Awheel c revolves and carries fo ward the rack frame lc, which also turns on the pivot Z, the movements are on diiferent centres asindicated red, figs. 4 and 5, and that the pin m rises on the projection n, and passes over at the moment the segment wheelz' has travelled over the rack j, when the operation on the paring knife is then again taken up by t segmental wheels d, as first described, and the wheelz' returns to the other end of the rack j, to resumei reverse action at the end'of the next, ,ha1f`revolution` of the bevel AWheel c', and thus continue the double actingoperation of the mach-ine. I

Havingthus fully described the construction and operation of my improvements, what I elaliln as new, and desire to secure by Letters Patent, isfv v 4 v 1. I claim the segmental wheels d d', in combination with the lever brake h, and the paring-knife arm f', constructed and arranged substantially as and for the purposes herein described.

2. I claim also the segmental wheel i, and the pin m, irl-combination with the eccentric rack frame la, and

rack j, eonstructed andlairanged substantially as and for lthe purposes herein sp`ecied.

3. I claim also the combination and arrangement o'f the bevel wheelc, with the segmental wheels ol d', the pin lm, the segmental wheel z', the eccentricy rack `frames 7c, .the lever brake h, and the knife arm f', constructed and operated substantially as and'for vthe purposesnherein set forth.
